MATRIX ASSEMIBLER FOR TYPOGRAPHICAL MACHINES.

Specification of Letters Patent.

Patented Nov. 11, 1919.

' Application filed May 31, 1919. Serial no. 300,988.

1 '0 all whom it may concern:

Be it known that I, GUs'rAvE RAPPRIOH, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in MatriX-Assemblers for Typographical Machines, of which the following is a specification.

My present invention relates to improvements in typographical machines and more especially to those of the class wherein the matrices drop from a magazine as they are released by the action of a keyboard and are conducted to an assembling point where they are assembled in a line preparatory to the casting operation. The primary object of the invention is to provide novel and improved means for conducting the matrices to the assembling point whereby obstruction to the passage of the matrices is avoided.

To this end the invention consists in certain improvements and combinations and arrangement of parts, all as will be hereinafter more fully described, the features of novelty being pointed out particularly in the claims at the end of the specification.

In the drawing Figure 1 is a perspective view of the assembling mechanism of a typographical machine, the same being constructed in accordance with the present invention.

Fig. 2 is a front view of a portion of the assembling mechanism as shown in Fig. 1, the front cover plate for the same being removed.

Fig. 3 is a perspective View of the delivery belt pulley.

Fig. 4 is a perspective view of the matrix chute.

Similar parts are designated by the same reference characters in the several views.

The present invention is applicable gen orally to typographical machines of the class wherein the matrices drop from a magazine when released by keyboard mechanism onto a traveling belt or equivalent means which serves to convey the matrices to a point where they are assembled into a line preparatory to the casting operation. The preferred embodiment of the invention is shown in the accompanying drawing and will be hereinafter described in detail, but it is to be understood that the invention is not restricted to the precise construction shown,

as equivalent constructions are contemplated and will be included within the scope of the claims.

In the present instance the assembling mechanism shown is of the type similar to that used upon machines of the linotype class, it comprising a plate 1 which serves to support parts of the assembling n'iechanism, this plate being located at the lower ends of passages which are formed between matrix -guiding fingers 2, the matrices dropping by gravity from the magazine through the spaces between these guiding fingers and thus reaching the assembling mechanism, the matrices from the magazine channels which are more distant from the assembling point being conducted to the assembling point by the aid of an endless belt 3 which is usually flat and which passes around or over a pair of pulleys, one of these pulleys 4E being shown. The matrices are delivered from the belt to a delivery chute 5, this chute serving to direct the matrices to the point where they are assembled into a line. The delivery chute 5 is composed preferably of a curved strip of metal, it being secured at 6 to a relatively fixed part of the assembling mechanism. and lying between the plate 1 and a front plate 7, the latter being pivoted at 8 whereby it may be swung into the position shown in Fig. 1 to permit access to the interior of the assembling mechanism.

According to the present invention, the pulley 4, unlike this pulley as heretofore constructed, is provided or formed with a pair of annular or peripheral flanges 9, the belt 3 lying in the space intervening between the flanges and the flanges project outwardly or radially from the belt engaging surface of the pulley for a distance sufli cient to enable the upper end 10 of the chute 5 to lie in the space between the flanges and in close proximity to the upper or outer surface of the belt, as will. be understood from Fig. 2. By so constructing the pulley and operatively relating the chute with the pulley and belt as described, a matrix leaving the belt 3. which matrix is designated M, is engaged by the peripheral flanges 9 of the pulley, these flanges on the pulley lifting the matrix from the belt and such flanges on the pulley convey the matrix to the chute 5, avoiding any possibility of catching of such matrix between the belt and the upper end of the chute. A matrix dropping from one of the matrix channels nearest theassembling point and which may be designated M in Fig. 2 is not conveyed to the assembling point by the belt, but it comes into engagement with the annular or peripheral flanges 9 on the pulley and these flanges on the pulley divert such matrix to the chute or the assembling point. In this case also there is no possibility of catching of such matrix between the matrix conveyer belt and the adjacent upper end of the chute.

-Ieretoforein machines of this class, the matrices have been transferred directly from the conveyer belt to the chute or equivalent part. Owing to the necessity of providing a clearance between the belt and chute, the matrices would occasionally enter the clearance space between the belt and chute, and, becoming wedged therein, would occasion delay in the operation of the machine and would sometimes cause damage. Thatfldifliculty, however, is avoided in a very simple and effective way by the present in- ;vention, the. flanges of the pulley preventing catching or wedging of the matrices in the clearance space between the conveyer and the adjacent upper end of the chute, the flanges on the pulley being sufficiently deep to permit the upper end of the chute to lie in the space between the flanges without, however, touching the belt, the matrices in eflect being directed to the chute through the medium of the flanges on the pulley.

What is claimed is 1. In a typographical machine, the combination of a matrix conveyer belt, a pulley over which the belt passes, the pulley having a peripheral flange which projects radially beyond the belt, and a matrix chute having a portion which extends inwardly beyond the peripheral edge of the flange and into close proximity to the belt.

2. In a typographical machine, the c01nbination of a matrix conveyer belt, a pulley cooperative with the belt, the pulley having a pair of annular peripheral flanges which project outwardly beyond the belt which lies between them, and a matrix chute having a portion which lies between said flanges and in close proximity to the belt.

3. In a typographical machine, the combination of a matrix conveyer belt, a pulley over which the belt passes, the pulley having a pair of annular peripheral flanges which are raised above the surface of the belt which lies between them, and means for guiding the matrices as they leave the belt, said means extending into a position between the flanges of the pulley and into close proximity to the matrix-supporting surface of the belt.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
